 * @see http://tools.ietf.org/html/rfc1929
 *
 * Once the SOCKS V5 server has started, and the client has selected the
 * Username/Password Authentication protocol, the Username/Password
 * subnegotiation begins.  This begins with the client producing a
 * Username/Password request:
 *
 *         +----+------+----------+------+----------+
 *         |VER | ULEN |  UNAME   | PLEN |  PASSWD  |

 *         | 1  |  1   | 1 to 255 |  1   | 1 to 255 |
 *         +----+------+----------+------+----------+
 *
 * The VER field contains the current version of the subnegotiation,
 * which is X'01'. The ULEN field contains the length of the UNAME field
 * that follows. The UNAME field contains the username as known to the
 * source operating system. The PLEN field contains the length of the
 * PASSWD field that follows. The PASSWD field contains the password
